A safe non-invasive technique for the measurement of gastric volume by real-time ultrasound is described. The application of this technique to the measurement of the emptying of liquid from the stomach is outlined. Gastric emptying of liquid was found to be log-linear, the mean half-life of emptying in 10 volunteers being 22 . 0 +/- 2 . 5 min. Ultrasound measurement of gastric emptying provides an opportunity to study the effects of drugs and disease on gastric motor function in man.
本文描述了一种通过实时超声测量胃容积的安全无创技术。概述了该技术在测量胃内液体排空方面的应用。发现液体的胃排空呈对数线性，10名志愿者的平均排空半衰期为22.0±2.5分钟。超声测量胃排空为研究药物和疾病对人体胃运动功能的影响提供了机会。
